Concrete meaning in the present invention.
It as shown in Figs. 1-2, is a kind of sealing structure for gauge-changeable wheelsets provided in an embodiment of the present invention comprising outer
Ring 1, inner ring 2 and resilient sleeve 3, the internal diameter of the outer ring 1 is greater than the outer diameter of inner ring 2, outer ring 1 is facilitated to be set in outside inner ring 2, described
One end of resilient sleeve 3 is fixedly connected with the inner circumferential of the outer ring 1, and the periphery of the other end of the resilient sleeve 3 and the inner ring 2 is solid
Fixed connection forms telescopic integral structure, and the outer ring 1 can drive the resilient sleeve 3 mobile relative to the inner ring 2, specifically
Ground, the outer ring 1 can be moved axially relative to the inner ring 2.Moving distance between outer ring 1 and inner ring 2 can satisfy
Relative movement distance when gauge changing between wheel 5 and axle 4, actual moving distance become equal to the gauge-changeable wheelsets gauge
The half of change, to realize the sealing between wheel 5 and axle 4, and also it is simple and compact for structure, it is easy for installation.
Further, as shown in figure 3, variable rail gauge wheel to include wheel 5 and axle 4, the wheel 5 slideably with institute
State the connection of axle 4, the internal diameter of the outer ring 1 and the hub outside diameter of the wheel 5 match, the internal diameter of the inner ring 2 with it is described
The outer diameter of axle 4 matches, and the outer ring 1 is for the fixed wheel hub for being set in the wheel 5, and the inner ring 2 is for fixing
It is set on the axle 4, saves sealing structure space to greatest extent, when gauge changing, outer ring 1 is moved together with wheel 5, bullet
Property set 3 using its shape changeabilities and restorability, follow outer ring 1 to move together, inner ring 2 is fixed, solves change
Wheel 5 and the sealing problem during 4 Relative sliding of axle, simple and compact for structure when gauge.
Specifically, the resilient sleeve 3 is preferably rubber cover, and the both ends of the rubber cover vulcanize respectively in the outer ring
In 1 inner circumferential and the periphery of inner ring 2, the thickness of rubber cover can select according to actual needs, and sulfuration process is in rubber
The cross-linking aids such as vulcanizing agent and promotor are added makes linear macromolecule be changed into three dimensional network under certain temperature, pressure condition
The process of shape structure, the structure connection after vulcanization are very reliable.
In the embodiment of the present invention, the length of the outer ring 1 is greater than the length of the inner ring 2, allows outer ring 1 complete
Inner ring 2 is coated, occupied space is minimum at this time, saves space.
Wherein, it is formed between the outer ring 1, resilient sleeve 3, inner ring 2 and the wheel hub, axle 4 for encapsulating lubricating oil
Space encapsulates lubricating oil within this space, to keep the continuous lubrication between wheel 5 and axle 4, avoids inner ring 2, outer ring 1
Between the sealing part abrasion that generates by relative movement, and good seal performance, No leakage.
It should be noted that the wheel 5 is connected with axle 4 by spline fitted, and specifically, the connecting hole of wheel 5
Equipped with internal spline, axle 4 is equipped with external splines, wheel 5 and axle 4 and is cooperatively connected by internal spline and external splines, by torque
It is evenly distributed on 5 circumference of wheel, both convenient for transmitting torque, wheel 5 is also convenient for along axle 4 and slides realization gauge changing.
Wherein, the gauge-changeable wheelsets further include retaining mechanism 7, and the retaining mechanism 7 is set to the outside of the wheel 5,
And be fastenedly connected with the outside of the wheel 5 by fastener, for the locking and unlock of wheel 5, to realize that wheel 5 converts rail
Away from structure is simple, easy to operate.
Wherein, the retaining mechanism 7 is separately mounted in the axle box 6 at 4 both ends of axle, saves installation space, tool
Body, the internal surface gaps of the retaining mechanism 7 and the axle box 6 cooperate, and enable retaining mechanism 7 with respect to axle box 6
Horizontal sliding；By the way that the sealing structure is arranged, occupied space is less, and is unlikely to influence to be mounted in wheel 5 in extreme position
The gear box structure of side.
In the embodiment of the present invention, sealing structure is mounted on the axle on the inside of wheel, when gauge-changeable wheelsets are by standard gauge shape
When state is to broad gauge state change, the outside Slideslip of wheel 5, the outer ring 1 of sealing structure is displaced outwardly, and resilient sleeve 3 stretches out, such as
State shown in Fig. 2；When returning to standard gauge state, the outer ring 1 and inner ring 2 of sealing structure overlap, and resilient sleeve 3 is shunk, such as Fig. 1 institute
The state shown；It not only can guarantee that the translation of wheel 5 was unaffected in this way, but also sealing function can have been played, and space requirement very little.
As can be seen from the above embodiments, the configuration of the present invention is simple is compact, both can guarantee that the translation of wheel 5 is unaffected,
Sealing function, and space requirement very little can be played again, be properly arrived at lubrication, the sealing function of gauge-changeable wheelsets.
